Hydraulic disc brakes use barbed fittings to secure the hose to the lever and caliper. Those barbs need to seat fully inside the hose, and getting them there by hand ranges from difficult to impossible depending on the hose material and barb design. The Park Tool HBT-1 provides the mechanical advantage to press barbs into place consistently, without the fumbling and swearing that comes with trying to muscle them in with pliers or vice grips.

The tool works by clamping onto the hose while a threaded plunger drives the barb straight into the hose end. This controlled insertion prevents the angled entry that causes leaks and the crushed hoses that come from improvised methods. The design accommodates barbs from Shimano, SRAM, Hayes, Formula, and most other major brake manufacturers, making it a practical addition for shops and home mechanics who bleed their own brakes or replace damaged hoses.

Barb insertion is one of those tasks that seems simple until you're three attempts in with a mangled hose end and brake fluid everywhere. The HBT-1 eliminates the variables that cause those failures. The hose stays aligned, the barb goes in straight, and you move on to the actual bleed procedure instead of cutting off another inch of hose and starting over.... Read More
